1. Smart dog collars

Pet-friendly devices like Link’s AKC smart collar will monitor your dog’s location, body temperature and eating habits. The collar also tracks your dog's activity levels to ensure he/she is getting enough exercise for his breed, age and size. The device even has a remote-controlled light so owners can locate their pets in the dark.

“We feel strongly that the growing market of passionate and dedicated dog owners deserves technology that actually fits their lifestyle, and that of their dogs. We designed the LINK AKC smart collar with a distinct purpose to create a bridge that will take the bond between dog and human to new levels,” said Michael Basone, Chief operating officer of Link AKC.

The collar costs $149 along with a monthly subscription fee of $7.

2. LG 2017 OLED TVs with Dolby Atmos and Dolby Vision

Dolby's Atmos and Vision technologies can soon be experienced at home on LG's new line of televisions.

Dolby launched its Atmos surround sound technology in movie theaters in 2012. Its audio effects travel around a room, giving the user an authentic 360-degree auditory experience. Dolby’s Vision technology delivers “greater brightness and contrast, as well as a fuller palette of rich colors.”

“The fusion of Dolby Vision imaging and Dolby Atmos sound transforms your TV into an entertainment powerhouse,” the company said in a press release Wednesday.

“LG and Dolby share a passion for bringing the best possible audio and visual experiences to life,” said Kevin Yeaman, CEO of Dolby Laboratories. “This expanded collaboration with LG will bring together both Dolby Vision and Dolby Atmos and deliver spectacular experiences that consumers can see, hear, and feel.”

3. Kerastase Hair Coach

The smart hairbrush was created by parent company L’Oreal with French electronics company Withings and will reach stores later this year. The device uses a microphone and sensors to track users’ brushing techniques and offers individualized haircare tips via a connected app. The app gives users daily feedback on the health of their hair.

“The brush detects when it is being used and begins data collection automatically. As soon as you complete your brushing session, all data will be sent automatically to your phone via Bluetooth Low Energy or Wi-Fi,” Withings explained on its site.

The brush will cost $200.

4. Smart stores

Mega e-retailer Amazon was one of the first companies to enter the realm of smart shopping last month. The conglomerate is currently testing its Amazon Go store in Seattle, a grocery store model where shoppers scan their Amazon app when they enter. They won't be charged if they return the item. The program is still in beta and set to open to the public this year.

Stores like Lowe’s and Neiman Marcus are also experimenting with the smart store concept, and shopper-friendly technology like robot guides and virtual reality changing rooms will debut during this year's show.

5. Smart beds

Sleep Number's smart bed will put your 5-year-old mattress and box spring to shame. The bed self-adjusts through the night as its occupant changes positions by fluctuating the air in two mattress chambers. Using SleepIQ’s biometrics, the bed’s base helps prevent snoring by raising a person's head seven degrees.

“…we are excited to unveil the future of sleep: the Sleep Number 360 smart bed, a revolutionary product that redefines what people should expect from their bed,” said Shelly Ibach, Select Comfort CEO in a press release Tuesday.

Finally, the bed's smart alarm monitors its users' sleeping habits and wakes them while in lighter stages of sleep.
